Destroy target artifact or enchantment.
Revolt â€” If a permanent you controlled left the battlefield this turn, you gain 3 life.
Tokens that leave the battlefield will satisfy a revolt ability.
Revolt abilities donâ€™t care why the permanent left the battlefield, who caused it to move, or where it moved to. Theyâ€™re equally satisfied by an artifact you sacrificed to pay a cost, a creature you controlled that was destroyed by Murder, or an enchantment you returned to your hand with Leave in the Dust.
Revolt abilities check only whether a permanent you controlled left the battlefield this turn or not. They donâ€™t apply multiple times if more than one permanent you controlled left the battlefield. They donâ€™t check whether the permanent that left the battlefield is still in the zone it moved to.
If the target artifact or enchantment becomes an illegal target, Decommission doesnâ€™t resolve and none of its effects happen. You wonâ€™t gain life.
If Decommission destroys a permanent you control, it will enable its own revolt ability and youâ€™ll gain 3 life.
Energy counters arenâ€™t permanents. Paying wonâ€™t satisfy a revolt ability.
